Using the 'oncheck' utility to check the consistency of data and index pages for a table.
During this training we demonstrate how to use the 'oncheck' command line utility to to ensure that the data and index pages for a table are consistent. Any inconsistencies found must be repaired either via the mechanisms offered by the oncheck utility or via a manual process.

An experienced DBA will be keeping a close watch on the performance of the corporate database and will proactively be running scripts to monitor performance.
